A recording that has received little attention is a 2 CD set (Triart Recording TR012) of Josef Páleníček's complete music for piano and orchestra, including his 3 piano concertos and Concertino for Orchestra with Obbligato Piano (
https://www.triartmanagement.eu/en/internetovy-obchod/). I believe the recording of Concerto 1 is the first on CD and perhaps the first to be commercially released (a Czech Radio performance dates from 1971, but I don't think that was ever issued on LP or CD). The Concertino also appears to be a premičre release. The performances by Jitka Čechová and the Prague Radio SO under Ronald Zollman (Concertos 1 & 3) and Stanislav Vavřínek (Concerto 2 & Concertino) are outstanding, and the sound from 2014 is much better than what is on youtube of Concerto 1 and in the earlier Supraphon/Panton recordings by other pianists of Concertos 2 & 3. The recording of Concerto 1 is in the original scoring for piano, string orchestra, and timpani. The composer also made a version adding trumpet, 2 flutes, and oboe, which can be heard on youtube
played by the same pianist with the Czech Chamber PO Pardubice under Marek Štilec. There you can sample Jitka Čechová's virtuosity and musicality as well as Páleníček's compositional style.
